But we have consolidated version log in the cover-letter. Will include per-patch version log from next version. Below are the version log for v2: - "qcom,board_id" property is dropped. This is not the direct dependency for Ath12k AHB support, hence it can be taken up separately. - "qcom,bdf-addr" property is dropped in device-tree and moved to ath12k driver. - Currently we have only one compatible enum (qcom,ipq5332-wifi), hence conditional if() check for defining the binding is removed. - "reserved-memory" node is dropped from example DTS. - "status" property is dropped in wifi node of example DTS. >> .../net/wireless/qcom,ath12k-ahb.yaml | 293 ++++++++++++++++++ >> 1 file changed, 293 insertions(+) >> create mode 100644 Documentation/devicetree/bindings/net/wireless/qcom,ath12k-ahb.yaml >> >> diff --git a/Documentation/devicetree/bindings/net/wireless/qcom,ath12k-ahb.yaml b/Documentation/devicetree/bindings/net/wireless/qcom,ath12k-ahb.yaml >> new file mode 100644 >> index 000000000000..54784e396d7e >> --- /dev/null >> +++ b/Documentation/devicetree/bindings/net/wireless/qcom,ath12k-ahb.yaml >> @@ -0,0 +1,293 @@ >> +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) >> +# Copyright (c) 2024 Qualcomm Innovation Center, Inc.

In the IPQ5332 platform, the WiFi component, known as the Wireless Control Subsystem (WCSS), functions as the wireless controller. Additionally, there is a separate hardware module, the Qualcomm Hexagon DSP(q6 remote processor), which is utilized for offloading WiFi processing tasks. These two hardware modules operate in conjunction, necessitating a phandle in the WiFi node that references the remote processor. Despite their interdependence, these modules are distinct from a hardware perspective.
